GI.GstAudio.Objects.AudioBaseSrc

This is the base class for audio sources. Subclasses need to implement the create_ringbuffer vmethod. This base class will then take care of reading samples from the ringbuffer, synchronisation and flushing.

Exported types

newtype AudioBaseSrc

Memory-managed wrapper type.

class (GObject o, IsDescendantOf AudioBaseSrc o) => IsAudioBaseSrc o

Type class for types which can be safely cast to AudioBaseSrc, for instance with toAudioBaseSrc.

Defined in GI.GstAudio.Objects.AudioBaseSrc

toAudioBaseSrc :: (MonadIO m, IsAudioBaseSrc o) => o -> m AudioBaseSrc

Cast to AudioBaseSrc, for types for which this is known to be safe. For general casts, use castTo.

createRingbuffer

audioBaseSrcCreateRingbuffer

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc.

-> m (Maybe AudioRingBuffer)

Returns: The new ringbuffer of src.

Create and return the AudioRingBuffer for src. This function will call the create_ringbuffer vmethod and will set src as the parent of the returned buffer (see objectSetParent).

getProvideClock

audioBaseSrcGetProvideClock

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> m Bool

Returns: True if src will provide a clock.

Queries whether src will provide a clock or not. See also gst_audio_base_src_set_provide_clock.

getSlaveMethod

audioBaseSrcGetSlaveMethod

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> m AudioBaseSrcSlaveMethod

Returns: The current slave method used by src.

Get the current slave method used by src.

setProvideClock

audioBaseSrcSetProvideClock

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> Bool

provide: new state

-> m ()

Controls whether src will provide a clock or not. If provide is True, elementProvideClock will return a clock that reflects the datarate of src. If provide is False, elementProvideClock will return NULL.

setSlaveMethod

audioBaseSrcSetSlaveMethod

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> AudioBaseSrcSlaveMethod

method: the new slave method

-> m ()

Controls how clock slaving will be performed in src.

Properties

actualBufferTime

Actual configured size of audio buffer in microseconds.

getAudioBaseSrcActualBufferTime :: (MonadIO m, IsAudioBaseSrc o) => o -> m Int64

Get the value of the “actual-buffer-time” property. When overloading is enabled, this is equivalent to

get audioBaseSrc #actualBufferTime

actualLatencyTime

Actual configured audio latency in microseconds.

getAudioBaseSrcActualLatencyTime :: (MonadIO m, IsAudioBaseSrc o) => o -> m Int64

Get the value of the “actual-latency-time” property. When overloading is enabled, this is equivalent to

get audioBaseSrc #actualLatencyTime

bufferTime

No description available in the introspection data.

constructAudioBaseSrcBufferTime :: (IsAudioBaseSrc o, MonadIO m) => Int64 -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “buffer-time” property. This is rarely needed directly, but it is used by new.

getAudioBaseSrcBufferTime :: (MonadIO m, IsAudioBaseSrc o) => o -> m Int64

Get the value of the “buffer-time” property. When overloading is enabled, this is equivalent to

get audioBaseSrc #bufferTime

setAudioBaseSrcBufferTime :: (MonadIO m, IsAudioBaseSrc o) => o -> Int64 -> m ()

Set the value of the “buffer-time” property. When overloading is enabled, this is equivalent to

set audioBaseSrc [ #bufferTime := value ]

latencyTime

No description available in the introspection data.

constructAudioBaseSrcLatencyTime :: (IsAudioBaseSrc o, MonadIO m) => Int64 -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “latency-time” property. This is rarely needed directly, but it is used by new.

getAudioBaseSrcLatencyTime :: (MonadIO m, IsAudioBaseSrc o) => o -> m Int64

get audioBaseSrc #latencyTime

setAudioBaseSrcLatencyTime :: (MonadIO m, IsAudioBaseSrc o) => o -> Int64 -> m ()

Set the value of the “latency-time” property. When overloading is enabled, this is equivalent to

constructAudioBaseSrcProvideClock :: (IsAudioBaseSrc o, MonadIO m) => Bool -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “provide-clock” property. This is rarely needed directly, but it is used by new.

getAudioBaseSrcProvideClock :: (MonadIO m, IsAudioBaseSrc o) => o -> m Bool

Get the value of the “provide-clock” property. When overloading is enabled, this is equivalent to

get audioBaseSrc #provideClock

setAudioBaseSrcProvideClock :: (MonadIO m, IsAudioBaseSrc o) => o -> Bool -> m ()

Set the value of the “provide-clock” property. When overloading is enabled, this is equivalent to

No description available in the introspection data.

constructAudioBaseSrcSlaveMethod :: (IsAudioBaseSrc o, MonadIO m) => AudioBaseSrcSlaveMethod -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “slave-method” property. This is rarely needed directly, but it is used by new.

getAudioBaseSrcSlaveMethod :: (MonadIO m, IsAudioBaseSrc o) => o -> m AudioBaseSrcSlaveMethod

Get the value of the “slave-method” property. When overloading is enabled, this is equivalent to

get audioBaseSrc #slaveMethod

setAudioBaseSrcSlaveMethod :: (MonadIO m, IsAudioBaseSrc o) => o -> AudioBaseSrcSlaveMethod -> m ()

Set the value of the “slave-method” property. When overloading is enabled, this is equivalent to
